Title: Inspecting device using nuclear magnetic resonance
Inventor: YAMAMOTO ETSUJI
IPC: G01R33/54
Filed: 1984-10-03
Abstract: PURPOSE:To obtain a tomographic image with high quality by picking up an optional section in addition to a lateral and a longitudinal section without being influenced by the rising nor falling of a slanting magnetic field. CONSTITUTION:A controller 1 outputs various instructions to respective devices at constant timing. The output of a high frequency pulse generator 2 is amplified by an amplifier 3 to excite a coil 4. The coil 4 serves as a receiving coil, whose received signal is passed through an amplifier 5 and detected by a detector 6, and then converted into an image by a signal processor 7. Slanting magnetic fields in the Z direction and directions perpendicular to it are produced by coils 8, 9, and 10. The coils 9 and 10 establish the magnetic fields which cross each other at right angles. Then, respective components of a slanting magnetic field generated for inspecting a plane which cross none of the respective coordinate axes at right angles and respective components of a slanting magnetic field applied when a plane crossing the magnetic field at right angles is inspected are put together and applied without overlapping.

Title: Optical device provided with line-of-sight detecting function, and camera provided with line-of-sight detection function
Inventor: TAMURA SUSUMU
IPC: G03B7/00
Filed: 1996-07-18
Abstract: PROBLEM TO BE SOLVED: To accurately detect the line of sight by setting the final reflection surfaced of an optical member for forming an erect image as a light shielding surface excluding a luminous flux range effective to detect the line of sight and guiding only an infrared ray for detecting the line of sight to a line-of-sight detecting sensor. SOLUTION: Light shielding coating is applied to the part (hatched part) of an (e) surface mirror 14 being the final reflection surface excluding the luminous flux range 14b effective to detect the line of sight. A part of photographing luminous flux made incident from a photographing lens is reflected by a half mirror and transmitted through a screen on which subject light forms an image, enters a roof mirror and forms a finder image. In such a case, the infrared ray included in the photographing luminous flux enters the roof mirror in the same manner and is transmitted through all the surface of the field range of the mirror 14 so as to creep in a sensor for detecting the line of sight, but the luminous flux is mostly cut by the light shielding coating applied to the back surface of the mirror 14. Therefore, only the infrared ray reflected from an eyeball is transmitted through the mirror 14 and guided to the sensor for detecting the line of sight.

Abstract: PURPOSE:To reduce the abrasion of the inner surface of a burner tip, and to prevent the generation of coarse particles during atomizing by installing each first mixing chamber in the inward oblique direction so that extensions in the direction of injection of each first mixing chamber are crossed in a second mixing chamber. CONSTITUTION:Slurry-like fuel fed to a first mixing chamber 6 through the fuel distributing chamber 5 of a burner plate 4 from the fuel feed hole 2 of a burner plug 1 is mixed with an atomizing medium supplied to the first mixing chamber 6 of the burner plate 4 from the atomizing-medium feed hole 3 of the burner plug 1 and fed to the second mixing chamber 8 of a burner tip, and further mixed in the second mixing chamber 8 and atomized from a nozzle hole 9 and burnt. A mixture injected from a plurality of the first mixing chambers 6 is crossed in the second mixing chamber 8. Consequently, the mixture violently collides in the second mixing chamber 8 and is dispersed uniformly, is mixed sufficiently, and is ejected from the nozzle hole 9. In this case, abrasion of the burner tip 7 is reduced remarkably, and atomizing concentration is equalized. The generation of coarse particles during atomizing is prevented.

Title: High frequency switch circuit
Inventor: AIHARA SHIGENOBU
IPC: H03K17/687
Filed: 1983-11-02
Abstract: PURPOSE:To realize an FET high frequency switch circuit having a high isolation characteristic at OFF by grounding a gate terminal of an FET via a diode and a capacitor and turning on/off the diode by means of a control signal. CONSTITUTION:In biasing forward diodes 2, 3 by the control signal from a terminal 41, since the ON-resistance of the diodes 2, 3 is small, bypassing of a high frequency signal through inter-electrode capacitance of a transistor (TR)1 is prevented. When the bias to the diodes 2, 3 does not exist, the ON-resistance of the FET1 is decreased and the equivalent resistance of the diodes 2, 3 is larger, then the transmission loss between the source and drain is very small in comparison with the case when the TR is turned on. Thus, a high isolation characteristic is obtained between the source and drain when the FET1 is turned off.

Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To provide a system, for the nondestructive inspection of an RF circuit and for the retardation of an RF signal flow, which can reduce the time, labor and costs required for an inspection. SOLUTION: A system is used in connection with a first circuit component 101, with a second circuit component 103, with a microstrip line 107 by which the first circuit component 101 is coupled to the second circuit component 103 in such a way that RF electric power flows to the second circuit 103 from the first circuit component 101 through the microstrip line and with an RF inspection port 105 which is used to inspect an RF circuit. A first removable electric impedance is arranged so as to be physically close to the microstrip line in such a way that some RF electric power is reflected to the first circuit component 101 due to a mismatching operation because a first impedance mismatching operation is generated in the microstrip line.

Title: Radiation detector
Inventor: YOSHIDA YUZO
IPC: H01L31/00
Filed: 1987-08-20
Abstract: PURPOSE:To correct the detection sensitivity of incident radiation at a visual field position by forming respective radiation detecting elements so that their detection surfaces are narrower in area toward a center part in the thickness direction of the incident radiation crossing the parallel providing direction of them. CONSTITUTION:A fan beam X ray XB is transmitted through a sample PA and enters a detection cell of the radiation detector 10, but a fan beam X ray XB has a large intensity distribution DS decreased greatly nearby the edges. Thus, the arrival radiation decreases in intensity distribution on both ends surface sides in a slice direction S and the gathering electrode 12 of the cell is narrow in area toward the center part in the slice direction S and the sensitivity is suppressed lower at the center part than at the peripheral part, so a detection signal of nearly the same level with D' is extracted for C' as long as the same material is used at the end side P and center part O in the slicing direction S. Consequently, the unbalance of a radiation detection signal which is detected substantially can be corrected.

Abstract: PROBLEM TO BE SOLVED: To provide a thermal louver exhibiting high blade opening/closing response to temperature variation of an apparatus mounted on a satellite. SOLUTION: When a housing 6 incorporating a hydrogen storage alloy 7 is fixed to an apparatus 5 mounted on a satellite, temperature variation of the mounted apparatus 5 is sensed quickly by the hydrogen storage alloy 7 and hydrogen gas is absorbed/discharged.

Abstract: PURPOSE:To previously prevent breakdown of a thermal head and burning of peripheral parts and clearly specify the cause of these abnormalities by providing in a thermal printer a head protecting circuit having a head connection detecting means, a pulse width monitoring means and a CPU run-way monitoring means. CONSTITUTION:An output signal f' from an output side of an A/D converter 5 of 8 bits as a connection detecting means is inputted to a CPU 2. The CPU 2 monitors the signal f'. When it becomes FF, a connector unconnected state is determined and a drive stop signal b is made to be an L level. A head drive pulse width monitoring circuit 6 measures a time of the L level of a head drive pulse signal (a) by a reference clock CL. When the L level is held for more than a given fixed time, a head drive center signal C is outputted as the L level. On the other hand, a run-way monitoring circuit 7 monitors writing operation of the CPU 2. When the CPU is likely to write in an incorrect address, the circuit 7 regards it as a run-away of the CPU 2 and outputs a drive stop signal d as the L level.
